I need a wide band gauge, which of these kits do you recommend?
The Innovate LC-1/XD-16 or the PLX SM-AFR/DM5?

My plan is to replace the stock sensor with the wide band sensor and connect the ECU to the 0-1V output. I read somewhere that the output from the PLX was not as accurate as the Innovate LC-1?

 

I can't comment on the PLX bit I've run the Innovate equipment in all my cars over the last 4 years with very good results. Good price too at £238
